TTH FAMILY Three phase transformers for electrical medical installations.

TTH

Dry type resin cast transformer

Advantages of resin technology:

  • Protection against corrosive environments
  • Protection against high vibration levels
  • Protection against electrodynamic efforts
  • Reduction of noise level
  • Increase of product's lifespan

​Safety class I

Includes electrostatic screen between primary and secondary terminals and bimetallic temperature sensor

Includes also lifting eyebolts from X VA

Possibility of tailor-made manufacturing
